Ultrasonic surgical system having a fluid cooled blade and related cooling methods therefor
First Claim
1. A method of cooling an ultrasonic surgical instrument, the method comprising:
- insufflating a body cavity of a patient with insufflation media;
introducing an ultrasonic surgical instrument into the insufflated body cavity;
activating delivery of ultrasonic energy to the ultrasonic surgical instrument;
drawing insufflation media from the body cavity into the ultrasonic instrument; and
moving the insufflation media drawn from the body cavity through the ultrasonic surgical instrument to cool the ultrasonic surgical instrument with the drawn insufflation media.

Abstract
The present disclosure is directed to a fluid cooled ultrasonic surgical instrument and related systems and methods of use therefor. In some embodiments, the disclosed ultrasonic surgical instrument is adapted for used within an insufflated cavity or pneumoperitoneum of a patient. The instrument includes a housing having an elongate shaft, a waveguide disposed at a distal end of the shaft, a coolant inlet port defined in an outer surface of the housing, and a coolant pump disposed within the housing and configured to move coolant from the coolant inlet port to the waveguide. During use, insufflation gas from within the pneumoperitoneum is drawn into the instrument shaft by the coolant pump, and blown over the waveguide to provide cooling. The delivery of ultrasonic energy and activation of the pump may be controlled by a processor in response to user input and waveguide temperature.
